Fire extinguishing system for automotive vehicles
First Claim
1. A fire extinguishing system which comprises:
- a) a firing assembly for mounting to a container of pressurized fire extinguishing agent, the firing assembly including firing means responsive to an electric current for releasing the fire extinguishing agent from the container;
b) an optical flame detector for generating a signal in response to receiving radiation from a flame, wherein the optical flame detector is responsive to ultraviolet radiation having a wavelength of from about 180 nanometers to no more than about 280 nanometers; and
c) a control system for supplying the electric current to the firing means, the control system being responsive to the signal of the optical flame detector and having a manual control switch.

Abstract
A fire extinguishing system for vehicles homes and offices includes a firing assembly for attachment to a container of fire extinguishing agent, a firing pin for penetrating the container to release the fire extinguishing agent, the firing pin being moved by an explosive squib or a solenoid, a conduit for carrying fire extinguishing agent to a discharge outlet, and a control system having a capacitor for pulse discharge of electric power to the control head to fire the squib or solenoid. The control box includes a three-position switch for firing the system, putting the system on automatic function, or deactivating the system. Other switches can include sensors for activating the firing pin in response to high temperature, or vehicle impact. One or more optical flame sensors are employed with pulse counting electronic circuitry. Also included herein is an electropneumatic firing assembly employing a movable piston valve.
